Therefore, for the purpose of maintaining the stability of the entry in non-pillar longwall mining, we first present aroof-cutting method to optimize the entry roof structure in non-pillar longwall mining. Then,the deformation mechanism of the gob-side entry undergoing roof cutting issystematically studied by using numerical modeling. Subsequently, the stability control principles of entry stability in non-pillar longwall mining areproposed,and relevant support techniques aremade. Finally, numerical modeling and underground testswereconducted to evaluate the effect of the entry stability co
